This invention relate/sto a cute-lng com#4 a' central hollow -pedestal 11 upon the upper pound distribution system, particularly for wend of which a driving motor 12 is mounted,

continuous multiple -spindle turning maf chines of the type known in thetrade as a ContinLU-Ma'tic. An object o f the inven-` tion is to provide a" system adapted to distribute the cutting compound or lubricant in ane'ven and continuous manner to they cutting tools in contact with the work, and

l0`to continuously circulate-the compound, to=

' 15 from the cutting compound, thereby facilitating the removal of the cuttings and insurin a recirculation of the used compound in a c aried condition. Other objects are to provide adistribution system which may be economically built, conveniently installed vu onmachi'nes in process of manufacture or a ready in use, and which will require a minimum of attention on thepart of the operator.v

an embodiment of the invention is shown in the accompanying drawings, and this embodiment will be hereinafter more fully described with reference thereto, and the invention will be finally' pointed out in the claims.

V Referring to the drawings, the automatic machine in which thepresent cutting comund distribution system is incorporated 1s of the'icontinuous turning ty e, known in The machine comprises a base` 10,

With the above and other objects in view,

end with a tool operating cam 13. A rotat' able carrier 14 is mounted upon bearings 15 to rotaterelatively to the base and pedestal, and carrles a series of radially disposed rotatable work tables 16 upon which' the Work 1s secured by chuck 'aws 17, said jaws adapted'to be automatica ly operated vupon throwmg the lever 18, as disclosed more fully in myco-'pendm application Seix'No. 680,180. The work tab es are rotated from the motor 12 through a vertical shaft 19 in the pedestal and geared to said motor, and a vertical counter shaft 20 geared to and driven by tl 1e shaft 19 and which drives through its p1n1on 21 a ring .gear 22 mounted to rotate on the pedestal and meshing with the gears 23 of the worktable spindles. Tool slides 2a carrying tools 25 are mounted on the carrier in'relation to each of the Work tables, and are adapted to reciprocate during the rotation of the carrier through cooperation with the cam 13. The carrier is continurier, said Worm being driven by a suitable motor (not shown).

The cutting compound distribution system comprises a reservoir in the form of a relatively large pan 28 en aged beneath the base 10 of the machine and extending outwardly at all sides thereof, a pump 29 being disposed therein and adapted to force the liquid compound upwardly through a vertically Ydisposed pipe 30, the pump being provided with a laterally extending flange 31 secured to the base of the machine to iiX the position of the pump in the pan. The pump is driven by gearing disposed in a gear box 32 from a motor '33 mounted on va shelf 34 secured to the base 10 in raised relation to the pan.

In one corner lof the pan there is provided a removable relatively deep receptacle 35 adapted to receive the metal cuttings from the work, and perforated near its base, as at 35, to permit any liquid carried therein b the cuttings to drain into the pan 28. sectional metal cover 36 is provided over the remaining area ofthe pan, being supported inraised relation to the base of the pan, and with its inner and cuter ed spaced from the base 10 and the wall of e.

pan, by means of brackets 37 secured to the under surface of the cover sections resting on the base of the pan. The entire pef ri heral edges of the pan are thus surroundedp by a space through which the cutting compound, which is deposited thereon 'after use, will flow into the pan where 1t 1s recirculated through the action of the pump.

The carrier is provided at its upper end, and preferably as extensions of the tool slide supports, with a plurahty of suplporting standards 38, upon which an annu ar distributing reservoir 39 is supported b means of inwardly extending lugs 40 on said reservoir bolted to the supports, as shown clearly in Figs. 3 and 4. rIhe reservoir 39 is substantially horseshoe shape in cross section, and obviously rotates with and as a part of the carrier.

The vertical feed pipe 30 is provided at its upper end with an inwardly extendin portion 41 having a downwardly directe vertical nozzle 42 extendinginto the chan nel ring through the annular opening thereof, and adapted to continuously su ply the same with the cutting compound rom the pan 28.

At suitable points in theunder side of the reservoir ring there are secured a plurality of distribution pipes 43 extending verticali downward, and provided at their ends wit outlet nozzles 44 disposed in such relation to the tools and work as to continuously supply the cutting compound thereto. The noz zles 44 are provided with a rotary valve 45 of the type ada ted to be open in the downwardly dispose vertical position of the nozzle and to be closed upon swinging the nozzle upwardly so that any of the nozzles may be individually shut off when desired.

The carrier 14 is rovided below the work tables with an annu ar outwardly extending ledge or flange 46, the upper surface 47 of the carrier sloping downwardly thereto, while the mountin pedestals 48 for the work tables slope ownwardly to the surface 47, so that as the cutting com ound is flowed over the work and tools, 1t passes downwardly by gravity over the surfaces 48 and 47 to the ledge or flange 46, carrying the metal cuttings from the work with it.

A cylindrical skirt 49 supported and secured at its lower edge upon a series of projecting lugs 50 of the base 10, surrounds the flan e 46 with suilicient clearance between the inner surface of the skirt and the periphery of the flan e to permit the liquid cutting compound to ow downwardly over the periphery of the flange and along the inner surface of the skirt, and from which it drops upon the cover 36 and flows into the reservoir pan 28 over the edges of the cover, where it is recirculated through the system by the Lasarte pump. The skirt entends above the flange 46 for such height as to confine an splashin of the compound from the too s.

n order to control the amount of the liquid cutting compound in the reservoir 39 an overflow p1 e 5l is secured in the under surL face therco its lower outlet end being with in the skirt 49, while its upper end is at such height within the channel as to maintain a lever therein suliciently below the upper annular opening as to prevent any overflow or splashing out of the same as the rin is rbtated with respect to the submergef nozzle 42 of the feed pipe.

The metal cuttings from the work are confined upon the ledge 46 and are adapted as the carrier is rotated to be automatically removed and deposited in the rece tacle 35. For this purpose the skirt is provi ed above the receptacle with an opening 52 having its lower edge slightly below the lower surface of the flange, and provided with a downwardly directed inclined spout, the base portion 53 of which engages the lower edge of the openincr and extends beneath the flange 46, whi e the side ortions 54 are lianged, as at 55, and bolte at the sides of the o enin At the inner side of the skirt and a ong t ie edge of the opening forwardly of the direction of feed of the carrier there is secured an inclined or diagonally disposed dellector plate 56 enga in the-upper surface of the flange 46 an adgaptcd as the carrier rotates to deflect the cuttings from the flange onto the spout and into the receptacle 35. The deflector plate is preferably bent from the end of a circumferential band 57 extending about the inner surface of the skirt directly above the flange 46 and terminating at the rearward edge of the opening 52 and being adapted to elfectually prevent tlie cuttings from working their way over the edge o the flange, and also receiving such Wear throu h the abrasive action'of the cuttings7 as wou d otherwise be received by the skirt. l

.A cover 58 for the spout is hinged, as at 59, to the skirt at the upper side of the open-v ing, its side walls, which rest at their vertical edges upon tlie surface of the skirt, being spaced from the side walls of the spout so as to direct an cuttings which may overflow the sides of the spout into the receptacle. The cover may also be raised to permit convenient access through the opening to the flange for the purpose of cleaning cuttings there rom. A

From the fore oing it will be seen that the system, accor ing to the resent embodi-4 ment of the invention, provi es a stationary reservoir for the cutting compound, distribution means carried by and rotatable with the carrier for suppl ing the compound continuously to the wor tables, and circulationl means whereby the compound is continuoutlet ously circulated from the reservoir to the distribution means, from such means to the tools, and back to the reservoir. The invention further comprehends the improved means by which the cuttings are separated from the compound in a manner as to maintain the latter clean so that it may be repeatedly recirculat e I have illustrated and described a preferred and satisfactory 'embodiment of the invention as applied to a particular type of machine, but 1t will be obvious that it can also be applied and used on other makes of machines, and that changes may be made therein, within the spirit and scope thereof, as defined in the appended claims.
